ABSTRACT:
A permanent magnetic levitation apparatus comprises a permanent magnetic track unit and permanent magnetic levitation wing unit provided on a magnetic levitation vehicle and levitated above the track unit, in which the wing unit includes a ferromagnetic wing trough having an open bottom, a wing permanent magnet disposed in the wing trough, and non-ferromagnetic spacers which are disposed between the side walls of the wing trough and the wing permanent magnet, and the track unit includes a ferromagnetic track trough having an open top, a track permanent magnet disposed in the track trough, and non-ferromagnetic spacers disposed between the side walls of the track trough and the track permanent magnet, so that the wing permanent magnet and the track permanent magnet are disposed so that their poles with the same polarities face each other. With the above apparatus, the static magnetic energy is concentrated on the open top of the track trough and the open bottom of the wing trough so as to generate great repulsion forces.
